Question

Два автомобилиста выехали из одного и того же пункта одновременно а противоположных направлениях. Скорость одного автомобиля 78 км/ч ,а скорость другого 82 км/ч. Какое расстояние будет между автомобилями через 5 часов?

Answer 1

78×5=390
82×5=410
390+490=800 км будет расстояние

Answer 2

Вроде если S=V:t
Получается расстояние первого автомобиля равна 78*5=390.
Расстояние второго равна 82*5=410
И значит 390+410=800-это и есть расстояние

Answer 3

Calculation of Distance Between Two Cars

To calculate the distance between two cars that started from the same point at the same time but in opposite directions, we can use the formula:

Distance = (Speed of Car A * Time) + (Speed of Car B * Time)

Given that the speed of one car is 78 km/h and the speed of the other car is 82 km/h, and the time is 5 hours, we can substitute these values into the formula to find the distance between the two cars.

Distance = (78 km/h * 5 hours) + (82 km/h * 5 hours)

Calculating this equation will give us the distance between the two cars after 5 hours.

Let's calculate it step by step:

1. Calculate the distance traveled by Car A: 78 km/h * 5 hours = 390 km. 2. Calculate the distance traveled by Car B: 82 km/h * 5 hours = 410 km. 3. Calculate the total distance between the two cars: 390 km + 410 km = 800 km.

Therefore, the distance between the two cars after 5 hours will be 800 km.
